Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.
结果表明,1,拟南芥AtSIRT1与人的同源蛋白hSIRT4相同,定位于线粒体,可能参与呼吸作用和电子传递,SIRT2与人的同源蛋白hSIRT6相同,定位于细胞核,可能同它的功能类似,在延缓衰老及调节细胞寿命方面起作用。2,AtSIRT1突变,可引起幼苗和植株的子叶变黄和早衰;AtSIRT2突变,可引起叶片发紫,沉积大量花青素。3,SIRT蛋白的抑制剂Sirtinol不能表型模写AtSIRT1和AtSIRT2突变体,说明Sirtinol在拟南芥中的作用机制不同于其他生物。4,AtSIRT1和AtSIRT2蛋白质结构预测表明与已知的Sir2蛋白相似,揭示其功能的相似性。5,在大肠杆菌中过量表达了其中一个基因(AtSIRT2),可体外检测其酶学活性,进一步证明其功能。

The definitions of generalized directional derivative and generalized gradient of Lipschitz functions defined on Riemannian manifold are presented. Some properties of the directional derivative and gradient are proved by using tangent and cotangent mapping. The minimization necessary condition of nonsmooth Lipschitz functions is given. Moreover, Fritz John necessary optimality condition in mathematical programming is provided on Riemannian manifold.

Abstract] objective to identify the relationship between serum homocysteine and carotid artery atherosclerosis in patients with cerebral infarction and effects of foliate,methylcobalamin.methods the concentrations of hcy were determined by means of fluorescence polarization immunoassay and carotid arteries was examined with color doppler ultrasound in 165 patients with cerebral infarction.the subjects were divided into 4 groups according to the severity of lesion of carotid artery.the concentrations of hcy were compared in different groups.the patients with hyperhomocysteinemia received foliate and methylcobalamin.results when lesion of carotid artery became severer,serum hcy was higher.the intima medial thicknesses of carotid artery were significantly decreased in patients with hyperhomocysteinemia who received foliate and methylcobalamin for two years.conclusion hyperhomocysteinemia may play an important role in development of carotid artery atherosclerosis.the intervention of foliate and methylcobalamin may reduce carotid artery atherosclerosis.
摘要] 目的探讨脑梗死患者颈动脉病变与血清同型半胱氨酸水平的关系及叶酸、甲钴胺长期干预对其影响。方法对165例急性脑梗死患者进行血清hcy的测定及颈动脉超声检查,并按动脉硬化的程度分组,比较不同程度颈动脉粥样硬化患者hcy水平,部分高hcy血症患者给予叶酸、甲钴胺干预,随访2年。结果随着颈动脉病变程度的加重,血清hcy浓度呈上升趋势,高hcy血症干预者动脉内中膜厚度明显减小。结论高hcy血症对颈动脉粥样硬化的形成起重要作用,长期给予叶酸、甲钴胺干预可能减轻颈动脉粥样硬化。
